Of course, that's no guarantee - I belong to a religion where dating is a thing, and we believe marriage can be eternal, so there is a big emphasis on dating. And during my college years I was in an apartment of 6 and it seemed like every semester I'd have an engaged roommate - and I went on lots a dates, but didn't get married until I graduated.
So, yeah, go on lots of dates, and you might get married early. If not, don't sweat it. Just make sure you marry somebody who will work to have a good marriage.
note: I (and my culture) are definitely outliers - we tend to go through the courtship process relatively fast - I married my wife about 9 months after first meeting her.
In regards to dating, I was living in Provo, UT at the time, which over emphasized the dating aspect - I'm not sure how emphasized the dating aspect is outside of the U.S. / Angelo Saxon culture areas.
What I find rather interesting though is that despite placing more importance and weight on marriage, we tend to go through the courtship process faster (under a year is not uncommon).
I think it's really dependent on personal maturity. My wife-to-be and I both knew what we wanted families, so we looked at our financial situation, and decided we could responsibly get married while I was still in college. A couple generations ago, that was pretty normal. Not so much now, but that doesn't make it impossible.
Statistically, your divorce probability drops dramatically when you get married at 25, and doesn't change much afterward.
Once you're married at 25, the primary risk factors are: substance abuse (obvious), prior cohabitation (many people feel they "slide" into marriage when they do this), and unemployment.
This is... not exactly actionable advice for everyone ?
I think the parent's posting is more applicable than you might think - putting in the effort to go on dates and really get to know a person does a lot to cultivate romance.
Nothing kills romance like hanging-out, but my perception might be different than yours - my ideal romance leads to a life-long relationship, which takes the same kind of effort that the parent's suggestion called for (deliberate effort focus on a romantic relationship).
